The crystal structure of the title compound has been determined. PdC52H44N2P4, Mr = 927. 2, monoclinic, space group P21 /n, a =12. 102(2), b = 9.997(2), c=20. 254(5)(?),β=93. 80(2)°, V = 2445. 0(?)3, Z = 2, R =0. 075 and Rw = 0. 095 for 3535 observed reflections (I>3σ(I)), The palladium atom is located on the symmetric center and adopts a square planar coordination surroundings with two biphosphine ligands and two cyanide groups. The molecular structure in crystals is different from that in solution in which the molecule is very fluxional, probably due to the rapid alteration in coordination sites between the coordinated and uncoordinated phosphorus atoms of the biphosphine ligands. Their properties are also reported.

PdC52H44N2P4, Mr = 927 (?), β = 93. 80 (2) °, V = 2445.0 (?) 3, Z = 2, R = 0. 075 and Rw = 0. 095 for 3535 observed reflections (I> 3σ ) The palladium atom is located on the symmetric center and requires a square planar coordination surroundings with two biphosphine ligands and two cyanide groups. The molecular structure in crystals is different from from in solution where the molecule is very fluxional, probably due to the rapid alteration in coordination sites between the coordinated and uncoordinated phosphorus atoms of the biphosphine ligands.
